Moroso 07-11 Jeep 3.8L JK Air/Oil Separator Catch Can - Small Body - Billet Aluminum

This is the Moroso 85668 small body air/oil separator catch can, specifically made for the 2007 through 2011 Jeep JK models equipped with the 3.8L engine. Its main job is to catch oil vapor and blow-by gasses from the crankcase ventilation system before they get recirculated back into the intake. This helps keep your engine's intake tract cleaner, preventing carbon buildup on valves and in the combustion chamber, which can improve performance and engine longevity.

Constructed from solid billet aluminum, this catch can is built to last. The small body design is intended to fit in tighter engine bays, making installation more straightforward on the JK. Moroso is known for making well-built engine components, and this catch can is no exception. It features a durable finish and a design that aims to effectively separate oil from the air before it re-enters your engine.

When installing, you'll want to pay attention to how the hoses are routed to ensure a proper seal and efficient operation. Regularly checking and draining the catch can is also important to keep it working effectively. This part is a solid option for Jeep JK owners looking to maintain a cleaner engine.
